3.8 Auto-Tuning
Auto-Tuning uses motor characteristics to automatically set drive parameters for vector control. Think about the type
of motor, drive control method, and the motor installation environment and select the best Auto-Tuning method.
The keypad will show the messages with prompts to input the necessary parameter information. These prompts are
specified by the selected Auto-Tuning method and the control method setting in
A1-02 .

Auto-Tuning for Induction Motors
This section gives information about Auto-Tuning for induction motors. Auto-Tuning sets motor parameters E1-xx,
E2-xx ( E3-xx, E4-xx for motor 2).
Note:
Do Stationary Auto-Tuning if you cannot do Rotational Auto-Tuning. There can be large differences between the measured results and the
motor characteristics when Auto-Tuning is complete. Examine the parameters for the measured motor characteristics after you do Stationary
Auto-Tuning.

Rotational Auto-Tuning T1-01 = 0
• When you can decouple the motor and load the motor can rotate freely
while Auto-Tuning.
• When operating motors that have fixed output characteristics.
• When it is necessary to use motors that have high-precision control.
• When you cannot decouple the motor and load, but the motor load is less
than 30%.

Line-to-Line Resistance T1-01 = 2
•
After Auto-Tuning, the wiring distance between the drive and motor
changed by 50 m or more.
• When the wiring distance is 50 m or more in the V/f Control mode.
• When the motor output and drive capacity are different.

Input Data for Induction Motor Auto-Tuning
To do Auto-Tuning, input data for the items in Table 3.8 that have an "x". Before starting Auto-Tuning, prepare the
motor test report or record the information on the motor nameplate as a reference.
